Can not run or publish SQR jobs in Hyperion BI + 9.3.1

First time poster, long-time user and admirer of this and other Hyperion/Brio groups on ITtoolbox. The expert advice available here has helped me through countless Hyperion difficulties, thanks so much!

I have installed an instance of Hyperion BI+ 9.3.1 in test mode, and have used the Migration Utility to move our current 8.5 production system over to this test server. Everything seems to be working fine, except for our SQR reports/jobs that are published in the Workspace. They will not run, and I can not import or publish a new one.

If I try to import a new SQR job into the Workspace, no engines show up in the Import/Connectivity tab where the "Data Source and SQR Production Reporting Engine". When I finish the import procedure, I get the following message:

A general error was encountered contacting the server.
Detailed message: PR Engine, sqr version class not found.

Everything seems to check out fine in the Job Service (Factory) in the RSC. The PR Server is defined and points to the right /bin directory. All databases are defined as database servers and are also defined with connect strings in the job service. I have deleted the PR Server and database entries and readded them on the remote chance that something was corrupted in the install/migration, but no luck.

I can run an SQR report outside of the server in either the SQR Production Reporting Studio or in SQR (ODBC) Server. The report runs perfectly in both places.

Finally, here is the detailed error message that appears in the BrowseServlet log when I attempt to run a SQR job in Workspace:

To clarify my previous post to Franck, I had already declared my SQR engine and databases in both the JF and the RSC. That is what is so maddening about my problem, the error messages I'm receiving in the Workspace would indicate a setup problem in the RSC. However, everything is good there, I even went so far (as I described in my initial post) as deleting the databases/PR server and then re-adding them, just in case their was a corruption of some sort during the migration.

The SQR Production Report runs inside PR Studio and with SQR Server (ODBC), but it fails with the previously documented error messages inside the Workspace.

I have stopped and restarted services each time that I deleted and added the SQR Engine/JF-RSC databases in the RSC, but to no avail. I still can't run SQR jobs or publish them in the workspace, but can run them successfully from the studio or SQR server.

if you can not publish sqr in the workspace, then it is a configuration issue.
you should see the Logical name that you have declred within the JF when you publish an sqr job.
it seems that you have already some sqr job published. if you put the SB and the JF in debug
do you get some usefull messages ? when you execute an sqr
